Validation of the Finnish MD Anderson Dysphagia Inventory (MDADI) in patients with head and neck cancer.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The aim of this study was to translate and adapt the MD Anderson Dysphagia Inventory (MDADI) questionnaire into Finnish and validate it in patients with head and neck cancer (HNC). A total of 94 participants were included: 64 dysphagic HNC patients and 30 non-dysphagic age- and gender-matched controls. The MDADI was formally translated using the forward-backward method and feasibility, test-retest reliability, internal consistency, score distribution, known-group validity, and patient feedback and were analyzed. Criterion and convergent validities were tested against the previously validated dysphagia questionnaire F-EAT-10. The results showed good variability and no floor or ceiling effects in the dysphagic group (age range 31 to 85 years, mean 67.8, SD 11.2). In all MDADI subscales, the internal consistency reliability was high (Cronbach's alpha > 0.8). Moreover, the intraclass correlation in test-retest (n = 55) was high (> 0.9) in all subscales. The MDADI was able to discriminate between dysphagic and non-dysphagic participants: the mean total score was 73.6 for the dysphagic group and 99.9 for the control group (p > 0.001). The correlations between the MDADI and the F-EAT-10 were strong demonstrating criterion and convergent validities. Patient feedback of the MDADI was positive. In conclusion, the Finnish MDADI is a valid instrument to assess dysphagia-related quality of life in patients with HNC, offering enhanced clinical and research utility.
